Distance Calculator

Saudi Arabia’s Ministry of Transport and Logistic Services doesn’t publish a public town-to-town distance matrix, but it does maintain and document the official lengths of the Kingdom’s 8 major named controlled-access highways — a fact documented by Saudipedia, an encyclopedic reference citing the Ministry directly. This tool uses those 8 official lengths as its verified core: the Riyadh–Taif–Makkah Highway (820km), the Qassim–Madinah Highway (448km, connecting Buraydah), the Makkah–Madinah Highway (421km), the Jeddah–Madinah Highway (410km), the Riyadh–Dammam Highway (383km), the Riyadh–Qassim Highway (317km), and the short Makkah–Jeddah and Makkah–Taif highways (70km each).

Together these cover the Kingdom’s two most important corridors: the Hejaz cluster around Makkah, Madinah, Jeddah, and Taif — which carries enormous Hajj and Umrah pilgrimage traffic every year — and the central-to-eastern corridor linking Riyadh to Qassim and on to Dammam on the Gulf coast. Every route between two of these 9 hub cities that runs along one of the 8 named highways is marked “Verified route”, both in the calculator above and the table below.

Routes that don’t run along a single named highway end to end — including Riyadh to Jeddah itself, since no single official highway spans that exact pair directly — fall back to this tool’s GPS-based estimate, using the same Haversine correction factor calibrated against Nigeria’s full verified road matrix. The remaining 26 towns in this tool’s 35-city list — provincial centres like Abha, Tabuk, Ha’il, Najran, and Al-Ahsa (Al Hufuf), plus Eastern Province towns like Khobar, Dhahran, and Al Jubayl — are estimated the same way for any route touching them.
